Let’s talk about gas isolation valves in apartments, because this is one of those things nobody explains to you until something goes wrong.
What Is an Isolation Valve?
Imagine an isolating tap but for gas instead of water. That’s what we’re talking about here. It’s the little brass or stainless steel fitting on the gas line that feeds your cooktop, and you can turn it on or off whenever you need to.
Most people have absolutely no idea these exist until a gasfitter points it out or they need to use it. Which is kind of strange when you think about how important they are.
Why Australia’s So Strict About This Stuff
Here’s the deal with apartments: you’re not in a standalone house where a gas problem only affects you. You’re next to other people, sharing walls and services. One person’s gas issue can turn into everyone’s problem pretty quickly.
That’s why the rules around gas in apartments are really full-on compared to houses. According to Energy Safe Victoria, AS/NZS 5601 clearly states that every gas appliance needs its own isolation valve. Not a maybe, not a nice-to-have. Has to be there.
The Victorian Building Authority keeps updating these standards based on what they’ve learned over the years about keeping people safe. Each update makes things clearer and usually a bit stricter.
For apartments specifically, you can’t just have one valve for everything. Your cooktop gets its own valve. The hot water system>gets its own. The heater gets its own. And they all need to be somewhere you can actually reach them without needing a stepladder and a torch.
Why This Actually Matters
Think about it this way. Say your cooktop starts becoming problematic, maybe one of the burners won’t shut off properly, or you think you can smell gas around the stove. Without that isolation valve, your only option is heading down to wherever your gas meter or main gas isolation valve is, and shutting off everything.
No hot water. No heating. Nothing. All because your cooktop’s being difficult.
And in some apartment buildings, good luck even accessing the main gas meter or main isolation valve. With the individual isolation valve right there under your cooktop, you just reach in, turn it off, done. Two seconds. Everything else keeps working, you’re safe, and you can book a gasfitter to come have a look at it tomorrow instead of treating it like an emergency at 10pm.
If there’s a problem with just your cooktop, you can deal with it without affecting anyone else. Your neighbour doesn’t lose their hot water because you needed to shut something off. Strata doesn’t need to coordinate access. It’s just your problem, contained to your unit.

Finding Yours…
Most apartments have the cooktop valve in one of these spots:
Right up inside the cupboard under or next to your cooktop. Open the door, you’ll usually spot it pretty quick.
Honestly, just take a minute to find it now while you’re thinking about it. If you can’t track it down, that’s worth checking with your building manager or getting a gasfitter to have a look. According to NSW Fair Tradingand similar rules in other states, every gas cooktop in an apartment should definitely have one.
What You Should Actually Do
Whether you own your place or you’re renting, you really should know where this valve is. Not being dramatic, but you should also check that the handle actually moves. Give it a gentle turn (then turn it back). If it’s completely seized from sitting there for 10 years without being touched, it’s not going to help you when you actually need it.
Renters - if your place doesn’t have an accessible isolation valve, mention it to your landlord or property manager. This isn’t them being cheap, it’s literally required by law for gas safety.
Owners - if you’re getting any kitchen work done or replacing appliances, make your gasfitter check that your isolation valve is still good and meets current requirements. Standards change over time, so what was fine when your apartment was built might not quite cut it now.
Don’t Ignore Gas Safety
Gas isn’t something to be casual about, especially when you’re living in close quarters with other people. These regulations exist because people learned the hard way what happens when you don’t have proper gas isolation in multi-unit buildings.
Having a working isolation valve that you can actually reach isn’t asking much. It’s basic safety gear that protects you, your things, and everyone else in your building.

FAQs
Q: Where should gas isolation valves be located in my apartment?
A: Somewhere you can actually get to easily, usually in the cupboard right under or next to the cooktop. The whole idea is that if something goes wrong, you can reach it and turn it off quickly without having to shift furniture around.
Q: How often should gas isolation valves be inspected?
A: There’s no set schedule like ‘check it every three months’. But next time you have a gasfitter out doing work on your cooktop or hot water, get them to have a quick look at the valve while they’re there. And if you ever notice it’s hard to turn or looks rusty, don’t wait around and get it looked at.
Q: What’s the difference between the main gas shut-off and isolation valves?
A: Main shut-off turns off everything in your apartment - cooktop, hot water, heating, the lot. Isolation valves are for individual fixtures. So if just your cooktop’s playing up, you shut off that valve and everything else keeps running. Main shut-off is for proper emergencies or when you’re going away for months.
Q: What should I do if I smell gas near an isolation valve?
A: Don’t touch anything. Call an emergency plumber immediately.
